Ubuntu包

Question

我正在尝试在云端的Ubuntu机器上安装SciPy。以下是我遵循的步骤：

sudo pip install numpy
sudo apt-get install gfortran
sudo apt-get install libblas-dev
sudo apt-get install liblapack-dev
sudo apt-get install g ++
sudo pip install scipy

有关您的信息，它是Ubuntu 14.04，Python 2.7.6。我没有安装Python，它已经在机器中，就像pip和easy_install一样。这是pip.log：

pip文件：

__requires__ = 'pip==1.5.6' import sys from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('pip==1.5.6', 'console_scripts', 'pip')()
    )

easy_install文件：

#!/usr/bin/env /opt/bitnami/python/bin/python
# EASY-INSTALL-ENTRY-SCRIPT: 'distribute==0.6.34','console_scripts','easy_install'
__requires__ = 'distribute==0.6.34' import sys from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('distribute==0.6.34', 'console_scripts', 'easy_install')()
    )

请帮忙。

这是由gfortran编译器标志引起的吗？只是怀疑。

Answer 1

Ubuntu包

SciPy手册suggests the Ubuntu version instead of the pip version：

sudo apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose

PIP

另一种方法是installing the prerequisites：

sudo apt-get install python-pip python-dev build-essential
sudo pip install numpy
sudo apt-get install libatlas-base-dev gfortran
sudo pip install scipy

我刚刚在AWS Ubuntu 14.04计算机上对其进行了测试，经过长时间的大量警告编译后，一切似乎都能正常工作。

我通常建议使用后者，因为它适用于任何virtualenv，而前者在系统范围内安装包。

Answer 2

我可以通过更改此环境变量在bitnami上安装numpy / scipy：

export LDFLAGS="-shared"

然后安装到scipy的步骤是：

sudo apt-get update -y
sudo apt-get install python-pip python-dev build-essential
sudo pip install numpy
sudo apt-get install libatlas-base-dev gfortran
sudo pip install scipy

reference numpy issue

Answer 3

此问题仍然存在，因此我删除/opt/bitnami/python上的自定义安装并开始使用系统安装，现在一切正常

我使用

安装了scipy和numpy

sudo apt-get install python-numpy python-scipy

无法在生产服务器上安装SciPy
